Curtis,

I'm guessing that the restriction on Maxclient might do the trick.

Shortly after updating our TSM and Oracle servers to AIX 5.2, I started
using JFS2 for some of the file systems.  In a very short time, I saw page
file usage in the 60-70% range after YEARS of running less than 10%.  I
eventually tracked it down to the MaxClient% which sets the percentage of
memory used for file pages and caching of JFS2.  I had been setting
MaxPerm% but that only applies to JFS(1).

After restricting that parameter to about 30%, pagefile usage dropped to
its normal range of about 5%.  It is currently 4.6% as I write this.

We changed our settings to the following. I'll let you all know if this
fixes the problem in our case. Thanks for all the advice. So far so good.
After we made the changes, I stopped both instances of TSM, and the paging
space was reclaimed in about 5 minutes. It's sitting at 74.3% free now,
after a couple of hours. I'll give it a couple of days and report for
anyone who's interested.

Oh, and Richard.... still didn't get the size of the paging space
increased. The wet noodle flogging didn't work completely, but it got the
VM Tuning done!

1) Maxperm = 50%
2) Minperm = 10%
3) Maxclient = 20%
4) Strict_Maxperm = 1
